This video, part of a series on "Chance Discoveries" in chemistry, tells how three different chemists in two countries over the span of more than 30 years happened to make a white, waxy substance during lab experiments that, once recognized as potentially useful and developed, became polyethylene -- the most common plastic in the world.
